One of the best uses for the tankless electric heaters is radiant floor heat. I have a walk in shower with a concrete floor at grade level, and its heated very well with diy radiant loops and a little $200 Stebel electric tankless. Because its a continuous loop at pretty much a constant temp, it works killer in this application, and is half the cost of the dedicated units the radiant guys sell for this use. A little research reveals that its the same units that they relabel as "radiant".
